It was the third team-up between the the Sixth Doctor and Mel characters since their turn on television. It was notable for providing the first substantial details about Mel's family and general back story in performed Doctor Who. It was also unusual for not having a "villain" per se, and no real alien presence at all. Because of this, and its setting in 2003 and 1782, it was a "pure historical", even at the time of its release. The main "enemy" in the piece is actually the concept of the Grandfather Paradox, and the Doctor's efforts to retrieve Mel from her family's past history without causing damage to Mel's personal timeline.

The implication of the initial interior TARDIS scene is that Mel insisted that the Doctor change his outfit to attend the centenary celebration at the National Foundation for Scientific Research, and that he testily obeyed. Thus he likely was not wearing his traditional multi-coloured outfit for this adventure. However, the audio never makes clear exactly what he changed into, though the celebration was described as a "black tie affair."
